Relationships of the false date palm of the Florida Keys, with a synop-

 Contrib. Nat. Herbarium, 16 {1913). pt. 8, pp. VII+2JfS-25h pis. ^).— Though 

 the characters of the fruits and the germinating seedlings afford consistent

 to an independent position in the classification as representmg a new and dis- 

 tinct family. Pseudophoenicaceai. Outlines are given of a general treatment 

 of all the American palms.
